Abstract: A bulkhead (110) for separating an engine compartment (112) and a passenger compartment (114) including a support structure (320) including at least one reinforcement member (324) and a body (322) supported by the reinforcement member (324), a thermally insulative component (330) supported by the support structure (320), and an acoustic resonator (370) defining a plurality of openings that extend along a first direction from the thermally insulative component (330) toward the first resonator side and terminate at a location between the first resonator side and the second resonator side. The acoustic resonator (370) includes a plurality of cells that each defines a respective first open volume that is in fluid communication with at least one of the plurality of openings.
